QUESTION 1
Which address type does the IPv6 address FF05:0:0:0:0:0:0:2 specify?
A. unspecified
B. aggregable global unicast
C. link local
D. site local unicast
E. multicast
Correct Answer: E Section: (none) Explanation
Explanation/Reference:
Explanation: All IPv6 multicast addresses start with the first 8 bits of the address set to 1. Thus all multicast addresses start with the hexadecimal notation FF (1111 1111). The multicast range is as follows: FF00::/8 FFFF::/8 The second octet, following to the first octet of FF, identifies both the scope and the lifetime of the multicast address. In this way, IPv6 has millions of group multicast addresses to use in current and emerging technologies. Reference: CCNP Self-Study CCNP BSCI Exam Certification Guide p.112

QUESTION 78
You are the network administrator at Flydumps. You are in the planning stages of upgrading the Certkiller network, and need to decide which protocol to use. You need to choose a protocol that will meet the following goals: Supports classless routing Supports VLSM Does not rely on TCP/IP to exchange routing information Performs auto-summarization by default Allows for manual route summarization Which routing protocol should you implement on the Certkiller network?
A. BGP
B. EIGRP
C. OSPF
D. IS-IS
E. IGRP
F. RIPv2

Correct Answer: B Section: (none) Explanation
Explanation/Reference:
Explanation: EIGRP is a classless protocol that supports VLSM and performs auto-summarization of subnets by default. The subnet routes are summarized into a single network number aggregate. In addition, IP-EIGRP will allow aggregation on any bit boundary in an IP address and can be configured on a network interface for additional granularity. EIGRP also supports automatic summarization of network addresses at major network borders. There is an automatic redistribution mechanism used so IGRP routes are imported into EIGRP and vice versa. Since the metrics for both protocols are directly translatable, they are easily comparable as if they were routesthat originated in their own AS.

VLAN configured as the native VLAN for the port. Frames on the native VLAN are always transmitted
untagged and are normally received untagged. The default native VLAN isVLAN 1.
